Each of these pins is held in position by the engagement of the springor keeper 24: with a groove 2& formed around the respective pin and eachis out half way through as at 28 on a level with the bolt 20.Furthermore, each pin has extending through its top, a slot whereinslides a looking pin 28 held in set position so that one end of theother projects outwardly by a screw 28. Now, with one end of the lockingpin projecting outwardly the pins, when turned to bring that end againstthe upper shoulder of its opening 12, will allow movement of the boltthrough the gap 28" while, when turned to bring the pin in its oppositedirection a locking efiect will be produced. By setting the parts 28 inproper position it will be seen that certain of the indicia will have tobe turned upside down to per mit movement of the bolt. Consequently, anyone or more of these locking elements may be set so as to requirecertain of the pins 26 to be turned in one direction and the remainderin the other. For instance, referring to Fig. 10, it will be seen thatwhen the pins are turned in one position, they allow free movement ofthe bolt while, in any other position, they look the bolt. As forinstance, the pins in that figure lettered 26 lock the bolt, while thepins 26 are in position to let the bolt move. These pins can be soadjusted by means presently to be described that any particular numberof pins may be used for controlling the combination. That is to say, theindicia in any certain number of pins may be turned to known position toeffect release of the bolt. For instance, all of the indexes, which arehere shown as letters of the alphabet for convenience in distinguishingfrom the reference characters, may be required to be placed in uprightposition except, say, C, G and M, which may be arranged to be invertedto release the bolt. Now under these circumstances, unless this entirecombination is effected, the bolt cannot move. I The device has manyapplications, as for instance', it may be used for a door bolt beingmounted on a swinging door of the ordinary type, such as is indicated at30, the door closing against the jamb 31, and the bolt being providedwith a keeper 32 of ordinary construction.

Having thus described the invention, what is claimed as new is:

1. A base plate having a longitudinal channel extending therealong, aliner seated in said channel and having a similar longitudinal channel,a' cover plate extending over said liner, said liner, base plate andcover plate being secured together to form a longitudinal slot, alocking bolt slidable in said slot, said base plate, liner and coverplate being provided with aligned openings, said openings being arrangedto lie with their centers on the edges of the longitudinal slot, thebolt having semi-circular recesses spaced to conform to said openings,cylindrical pins extending through said openings and cutawavdiametrically opposite said bolt, heads on said pins having combinationindicia thereon, and means to hold said pins in said openings.

2. A base plate having a longitudinal channel extending therealong, aliner seated in said channel and having a similar longitudinal channel,a cover plate extending over said liner, said liner, base plate andcover plate being secured together to form a longitudinal slot, alocking bolt slidable in said slot, said base plate, liner and coverplate being provided with aligned openings, said openings being arrangedto lie with their centers on the edges of the longitudinal slot, thebolt having semi-circular recesses spaced to conform to said openings,cylindrical pins extending through said openings and cutawaydiametrically opposite said bolt, heads on said pins having combinationindicia thereon, means to hold said pins in said openings, other pinsextending centrally through said base plate, liner, cover and bolt, thebolt being provided with slotted openings terminating in circularopenings to accommodate the last mentioned pins.

3- A base plate having a longitudinal channel extending therealong, aliner seated in said channel and having a similar longitudinal channel,a cover plate extending over said liner, said liner, base plate andcover plate being secured together to form a longitudinal slot, alocking bolt slidable in said slot, said base plate, liner and coverplate being provided with alined openings, said openings being arrangedto lie with their centers on the edges of the longitudinal slot, thebolt having semi-circular rccesses spaced to conform to said openings,cylindrical pins extending through said openings and cutawaydiametrically opposite said bolt, heads on said pins having combinationindicia thereon, means to hold said pins in said openings, said coverplate being provided with a pair of longitudinal grooves, and keeperslocated in said grooves and holding said pins.

4. A base plate having a longitudinal channel extending therealong, aliner seated in said channel and having a similar longitudinal channel,a cover plate extending over said liner, said liner, base plate andcover plate being secured together to form a longitudinal slot, alocking bolt slidable in said slot, said base plate, liner and coverplate being provided with aligned openings, said openings being arrangedto lie with their centers on the edges of the longitudi nal slot, thebolt having semi-circular recesses spaced to conform to said openings,cylindrical pins extending through said openings and cutawaydiametrically opposite said bolt, heads on said pins having combinationindicia thereon, means to hold said pins in said openings, said coverplate being provided with a pair of longitudinal grooves, other pinsextending centrally through said base plate, liner, cover and bolt, thebolt being provided With slotted openings terminating in circularopenings to accommodate the last mentioned pins, and keepers located insaid grooves and securing said pins.

In testimony whereof I aflix my signature.
